Grow Mediums 3.5 gallon DWC bucket too small?

[Smeghead]

Will a 3.5 gallon bubbling bucket work well for DWC and autoflowers? Will it be okay for monsters like Think Different and Auto Mazars?

Im using a 2 gallon dwc bucket and doing ok its just more work changing out the water and keeping the PH balanced because the plant sucks up a lot of water. It depends on how big of an area you have to grow in my box is 20"x 20" x 4' so my height is limited therefore I needed to use a shorter bucket if you got the height I would use a 5 gallon bucket more volume of water is always better. This is mine at 37 days

What strain do you have going there? I got 2x 3.5 gallon buckets and I think I'll use that for smaller yielders or low ryders and I'll get a 5 gallon for the Dutch Passions and big yielders. Is yours root bound yet? What's the size of your root mass right now? How do you keep your rez water cool? And most importantly, what's your expected yield, smaller like DWCocha says?

Question: Could I use Coco nutes in a DWC grow? The NPK for veg is 21-10-35 and the NPK for bloom is 19-11-35.
